Expert ADVICE
How to successfully implement zBX hybrid computing
George Ng is a
senior certified
IT managing
consultant for
IBM Systems and
Technology Group
Lab Services.
Richard Young is
a senior certified
executive IT
specialist with
IBM Systems and

System z Lab
Services.

T

he IBM zEnterprise* System-the logical integration of System z*
central processing with zEnterprise Unified Resource Manager and
zEnterprise BladeCenter* Extension (zBX)-has been deployed in
multiple industries worldwide to solve various business problems.

For a quick and successful
implementation, it's important
to understand requirements,
what's supported and what's
recommended. The IBM Systems
and Technology Group System z
Lab Services team has assisted
in many zBX implementations.
Accordingly, the team offers
lessons learned to assist clients.

First Steps
Key benefits of this hybrid
computing solution include
reduced complexity, labor and skill
requirements, and the capability
to manage workloads on virtual
servers across heterogeneous
hardware platforms. For
organizations ready to integrate
zBX into their data centers,
the first question to ask is:
What's required for a successful
deployment? Several factors can
significantly affect the outcome, so
to start off right:

1

Plan for hybrid teams to participate in and pay careful attention to
the technical delivery assessment
(TDA) and solution assurance
product review (SAPR).
2 Understand the supported
and recommended network
connectivity options to the zBX
top-of-rack (TOR) switches.

3

Know the supported storage
devices and connectivity options.
4 Identify applications that are
good deployment candidates.

Cooperative Planning
Early involvement of all affected
cross-platform support and
operational organizations is
essential. An IT department's
culture can impact the
deployment of technologies,
business applications and
productivity. Organizational
boundaries based on hardware
or OS platform might exist.
Therefore, teamwork across these
lines increases productivity and
efficiency, and it fosters a broader
awareness of how applications
operate and serve the business.
A hybrid computing solution
often necessitates bringing
together teams to integrate the
deployment and operational
control of the system. The
importance of involving all teams
in a zBX enablement early in the
process can't be understated.
Doing so helps to not only engage
the teams but also enable them to
contribute productively. Each team
will have a deeper understanding
of its own platform (e.g., network,
storage or processor platform),
and can contribute insight and

raise awareness of the rest of the
implementation team.
IBM will conduct a preinstallation TDA to help clients
understand the installation and
deployment requirements of the
zBX. SAPRs provide the product
information, checklists and
guidelines to be followed during
the TDA.
A zBX TDA is performed as
part of the zEnterprise TDA, but
the two aren't interchangeable.
The zBX TDA must include other
teams, like those responsible for
distributed storage, networking
and OS support. Topics will
include storage requirements for
N_Port ID virtualization (NPIV),
cable distances, physical network
connectivity and supported blade
OSs-areas sometimes unfamiliar
to z/OS* systems programmers.

Connectivity Options
In addition to the physical
connectivity planning, pay
particular attention to the zBX
network security requirements,
availability architecture and,
perhaps most importantly, Layer-2
(L2) and Layer-3 (L3) connectivity
options. Prior to July 23, L3 (router
type) connections were the only
supported type of "external"
connections to the zBX intra-
